Abstract
The utility model discloses a balance shaft of an automobile balanced suspension system. The balance shaft comprises balance shaft support spindle sections correspondingly at the left side and the right side and counteractive rod head connecting sections at the left side and the right side, wherein the special middle section of the balance shaft is a cylinder, and the middle section of the balance shaft is milled and flattened to have a big cutting surface; and the balance shaft adopts an integral casting structure. The balance shaft of the automobile balanced suspension system adopts the integral casting form, bad cracking of a welding part between a flatten part of a casting tube as well as the casting tube and each counteractive rod head cannot occur; as the original large-scale die forging is changed into an alloy steel integral casting, the balance shaft of the automobile balanced suspension system, disclosed by the utility model, has the advantages of avoiding investment of large-scale forging and pressing equipment, reducing blank manufacturing difficulty, saving material and reducing production cost.
Description
Technical field
The utility model relates to field of automobile, specifically, relates to a kind of automobile balance suspension system balance shaft.
Background technology
Balance suspension assembly product is applied to more than 13 tons in the commercial autotruck mostly, on the back axle; Wherein balance shaft is the important spare part in the connection shaft support assembling component; Connection shaft support assembling component be assemblied in multi-wheeler in, on the back axle, in the assurance, all wheels of back axle all with ground have good contact reach in, each wheel vertical load of back axle is equal.And balance shaft is the lever that is equilibrated at the redistribution of left and right wheels vertical load.
In the prior art, automobile balance suspension system balance shaft is that a hollow cast tube thick-walled pipe and two back reaction rod head foundry goods welding backs are synthetic.Its back reaction rod head is as shown in Figure 1.Cast tube two ends car becomes to cooperate seam, and middle two ends are flattened the processing mode that flattens through heating and met design requirement, and then the back reaction rod head are pressed into the cast tube seam and get final product.
But; Existing automobile balance suspension system balance shaft structure needs the input of special-purpose large-scale forging equipment; And the blank manufacture difficulty is big, and productive costs is high, and bad cracking can appear in cast tube flattening position and cast tube and back reaction rod head seam position simultaneously; And then cause the inefficacy of part, cause potential safety hazard for the cruising of automobile.
The utility model content
To above-mentioned deficiency of the prior art; The utility model has been taked to solve existing lathe and has been produced the input that automobile balance suspension system balance shaft needs large-scale forging equipment; Equipment has high input, and the blank manufacture difficulty is big, and productive costs is high; The difficult problem of bad cracking can appear in cast tube flattening position and cast tube and back reaction rod head seam position simultaneously, and a kind of suspension system of automobile balance efficiently balance shaft is provided.
The technical scheme that the utility model is taked is:
A kind of automobile balance suspension system balance shaft comprises that left and right sides cooresponding balance shaft supports main shaft section and left and right sides back reaction rod head linkage section form, and the special interlude of said balance shaft is a cylinder.
Said balance shaft interlude is that the big facing cut that cuts off is flat; Said balance shaft adopts the inblock cast structure.
The advantage of the relative prior art of the utility model and beneficial effect:
The utility model automobile balance suspension system balance shaft adopts the inblock cast form, cast tube can not occur and flatten position and the bad cracking of cast tube and back reaction rod head seam position; Large-scale die-forged part by original changes the alloy steel mono-block cast into, has avoided the input of large-scale forging equipment, has reduced the blank manufacture difficulty, has practiced thrift material, has reduced productive costs.
Description of drawings
Fig. 1 is the split type back reaction rod head of a prior art foundry goods master TV structure scheme drawing;
Fig. 2 is the automobile balance suspension system balance shaft master TV structure scheme drawing of the utility model.
Major part nomenclature in the accompanying drawing:
Among the figure:
1, right side balance shaft supports main shaft cervical part of esophagus 2, left side balance shaft supports main shaft cervical part of esophagus
3, right side back reaction rod head 4, left side back reaction rod head
5, heavy in section plat mill section; 6, back reaction rod head
The specific embodiment
Followingly the utility model is carried out detailed explanation with reference to accompanying drawing and embodiment:
Accompanying drawing 2 can be known; A kind of automobile balance suspension system balance shaft; Comprise the cooresponding left side of left and right sides balance shaft supports main shaft cervical part of esophagus 2 and right side balance shaft supports main shaft cervical part of esophagus 1, left side back reaction rod head 4 is formed with right side back reaction rod head 3 linkage sections, and the special interlude of said balance shaft is a cylinder.Said balance shaft interlude is the big facing cut flat 5 that cuts off; Said balance shaft adopts the inblock cast structure.
The utility model automobile balance suspension system balance shaft adopts the inblock cast form, cast tube can not occur and flatten position and the bad cracking of cast tube and back reaction rod head seam position; Large-scale die-forged part by original changes the alloy steel mono-block cast into, has avoided the input of large-scale forging equipment, has reduced the blank manufacture difficulty, has practiced thrift material, has reduced productive costs.
The utility model automobile balance suspension system balance shaft; Comprise middle part straight tube main shaft section and the back reaction rod head part that lays respectively at both sides; Adopt disappearance mould technology inblock cast, adopt the meticulous quality of foundry goods outward appearance after cast steel material is cast good, through the strength optimization design of Simulation; Therefore can reduce a certain amount of oad, practice thrift steel and reduce deadweight.
The utility model adopts integral type balance shaft New Casting Technique; For the formulation of two side shaft journal process for machining, also be vital, after handling through stress peening behind the balance shaft integral casting forming; At first adopt face miller to mill the balance shaft end face; Use the centre hole at centre hole special plane or lathe spooling two ends then, front and back add top centering center, center on lathe at last, and this lathe adopts Four-jaw chuck to grasp the I-shape end face of back reaction rod head with 2 pawls.Through the lathe cross tool carriage balance shaft crank journal is carried out turning processing, cut a side and then changed and turn around, process other end crank journal with identical method.Original technology and drawing furnace etc. can be still used in the heat-treatment quenching of balance shaft, tempering.
